Some services, such as CPVLab, require you to update the "A" record for a DNS zone. If you're using Hostwinds or another company for DNS hosting services, the following information should prove helpful in successfully updating your DNS zone appropriately.
If your Authoritative Nameserver provider where your nameservers are pointed to is not listed below, the general idea is summarized below:
In most cases, changing an existing A record rather than adding a new record should be the same, except you'd see information for the record you're changing already populated. You'd change this information rather than add a new A record.
Your DNS information, such as your A record, is held and managed by your Authoritative Nameserver provider. In most cases, this is a web hosting provider such as Hostwinds, although you can always perform a WHOIS lookup on your domain name to confirm where your nameservers are pointed to so that you can make the necessary changes to your DNS.
cPanel also offers advanced zone editor and simple zone editor, which will allow the adding or editing of "A" records as well.
Unless otherwise indicated, settings such as TTL (Time To Live) should be OK to leave as the default setting. However, before changing your DNS, we suggest lowering the TTL to 300 if your Nameserver provider allows that and waiting until the TTL has expired before making any DNS changes to reduce DNS propagation times.
DNS changes may or may not immediately occur. Generally speaking, most sites use a TTL (Time To Live) of a few hours. However, in extreme cases or cases where the nameservers have also recently changed, it may take up to 72 hours to take effect.
